Likewise, which objective has the smallest depth of field?
Microscope Notes
- The eyepiece, also called the ocular lens, is a low power lens.
- The objective lenses of compound microscopes are parfocal.
- The field of view is widest on the lowest power objective.
- The depth of focus is greatest on the lowest power objective.
- The amount of light transmitted to your eye is greatest at the low power.
Likewise, what is the working distance of an objective? Objective Working Distance. Microscope objectives are generally designed with a short free working distance, which is defined as the distance from the front lens element of the objective to the closest surface of the coverslip when the specimen is in sharp focus.
Herein, what is the working distance for a 10x objective lens?
A 10x objective can have a WD of several millimeters (4-10mm, or 4000-10,000um). A well corrected, high NA 20x dry objective will have a WD of slightly less than 1mm (1000um). Most well corrected, high NA 40x and 60x oil objectives have working distances on the order of 0.1mm (100um).
